This afternoon we published our interview with architect and urban designer Hella Hernberg, author of Helsinki Beyond Dreams, an inspiring book that showcases the Finnish capital’s flourishing grassroots culture. We’re happy to give away a copy of Helsinki Beyond Dreams to one of our lucky readers! The only thing to do is subscribe to Pop-Up City Daily, our new daily email newsletter with the latest updates from the blog. That’s easy, huh?
